Working with Mercedes-Benz FBS3/FBS4 ISM and DSM gear shift modules often requires correct module connections before programming or matching can begin. OBDSTAR C1033 Dedicated Harness provides a ready-made plug-and-play connection for these modules and can be used both on the vehicle and on the workbench.
